Answer:
Step-by-step explanation:
First, you need to get the equation into y = mx + b form, like this:
Add y to both sides to get y + 2x − 5= 0
Then subtract 2x to get y - 5 = -2x
Add 5 to get y = -2x + 5
Now we know the slope is -2, or -2/1.
A line that is perpendicular to it has a slope that is the first line's slope's opposite reciprocal. This means flip the fraction upside down and change the sign, which gives you positive 1/2.
